Ksenya-84 [330]

Answer:

21.759

Step-by-step explanation:

Given that :

Mean (m) = 25

Standard deviation (s) = 12.5

Sample size (n) = 40

α = 90%

The confidence interval is obtained using the relation:

Mean ± Zcritical * s/sqrt(n)

Zcritical at 90% confidence interval = 1.64

25 ± 1.64 * (12.5/sqrt(40))

Lower boundary : 25 - 1.64(1.9764235) = 21.75866546

Upper boundary : 25 + 1.64(1.9764235) = 28.24133454

(21.759, 28.241)

Hence, lower bound of confidence interval is : 21.759

satela [25.4K]

Given:

Speed limit on a highway is 110 km per hour.

Let x be the speed of the car in time 't'

$t\ge\frac{x}{110}$

time when taken for a car to travel 132km.

$\begin{gathered} t\ge\frac{132}{110} \\ t\ge1.2\text{ hours} \end{gathered}$

It takes minimum 1 hour 12 minutes
